这是我的代码：
public List<Player> PlayerList { get; set; }
public A1_ResultWnd()
{
InitializeComponent();
//GenerateColumns();
}
private void GenerateColumns()
{
Grid.AutoGenerateColumns = false;
DataGridViewColumn miejsce = new DataGridViewColumn();
miejsce.DataPropertyName = "Miejsce";
miejsce.HeaderText = "Miejsce";
miejsce.Name = "miejsceCollumn";
DataGridViewColumn imie = new DataGridViewColumn();
miejsce.DataPropertyName = "Imie";
miejsce.HeaderText = "Imię";
DataGridViewColumn uid = new DataGridViewColumn();
miejsce.DataPropertyName = "UID";
miejsce.HeaderText = "UID";
DataGridViewColumn rasa = new DataGridViewColumn();
miejsce.DataPropertyName = "Rasa";
miejsce.HeaderText = "Rasa";
DataGridViewColumn sex = new DataGridViewColumn();
miejsce.DataPropertyName = "Sex";
miejsce.HeaderText = "Płeć";
DataGridViewColumn klan = new DataGridViewColumn();
miejsce.DataPropertyName = "Klan";
miejsce.HeaderText = "Klan";
DataGridViewColumn strefa = new DataGridViewColumn();
miejsce.DataPropertyName = "Strefa";
miejsce.HeaderText = "Strefa";
DataGridViewColumn status = new DataGridViewColumn();
miejsce.DataPropertyName = "Status";
miejsce.HeaderText = "Status";
Grid.Columns.Add(miejsce);
Grid.Columns.Add(imie);
Grid.Columns.Add(uid);
Grid.Columns.Add(rasa);
Grid.Columns.Add(sex);
Grid.Columns.Add(klan);
Grid.Columns.Add(strefa);
Grid.Columns.Add(status);
}
private void A1_ResultWnd_Shown(object sender, EventArgs e)
{
GenerateColumns();
Grid.DataSource = PlayerList; //Here the exception occures
}
PlayreList不是空的。
PlayreList is not empty.
推荐答案
您需要给列的类型。如果你想要一个文本框列，你必须使用新DataGridViewTextBoxColumn（）。比方说，你想有一个文本框和一个组合框，你必须在以下几个方面：
You need to give the type of the column. If you want a textBox column, you'd have to use new DataGridViewTextBoxColumn(). Let's say you want a textBox and a combobox, you'd have the followings:
另外，你一遍又一遍呼唤第一列名
also, you are calling the first column name over and over again.
DataGridViewColumn miejsce = new DataGridViewTextBoxColumn();
miejsce.DataPropertyName = "Miejsce";
miejsce.HeaderText = "Miejsce";
miejsce.Name = "miejsceCollumn";
更改为给定的名字下面。
Change the following for the given name.
DataGridViewColumn imie = new DataGridViewComboBoxColumn();
imie.DataPropertyName = "Imie";
imie.HeaderText = "Imię";
imie.Name = "imieCollumn"
